Given numbers are 140, 398, 347, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 398) = 27860
GCD(140, 398) = ( 140 x 398 ) / 27860
= 140 / 398
= 140
Step2:
LCM(2, 347) = 694
GCD(2, 347) = ( 2 x 347 ) / 694
= 2 / 347
= 2
Step3:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
So, Greatest Common Divisor of 140, 398, 347, 917 is 1
